Patent AT-E39183-T1 (AT)
Inventor: HALLQVIST STEN

Abstract: The disclosure relates to an automatic gun which employs case ejectors (1, 1') for realizing extraction and ejection of the cartridge case from a spent round. The case ejector is also utilized for arresting the breech block during the recoil of the weapon and holding the breech block in an open position so that ramming home of a new round (3') may be executed. The ejector is exposed to the round in process of being rammed home, which round, during its thrust towards the homed position in the barrel, entrains the ejector so that the breech block (2) is released and may execute its closing movement int. al. with the assistance of spring means placed under tension during the opening movement of the breech block. The ejector and the breech block are designed with cooperating arrest and abutment surfaces which take up portions of the kinetic energy of the round which is in the process of being rammed. A separate buffer device (5) is also connected to the ejector, by means of which device the above-mentioned retardation/cushioning may be amplified. By such an arrangement, the feeding and ramming speed of the gun may be increased without the risk that each respective round jolt against the rear face of the barrel and derange the breech block in its closing cycle. Such a derangement would occasion cease-fire.

Abstract: The invention relates to a process and apparatus for the casting of metal strands, more particularly in the form of strips. The molten metal emerging from a slotted die 2 is applied to the cooling surface of a cooling member 1 which is moved past the slotted die 2. Allowing for the law of solidification, at the start of casting the strip outlet side die lip is gradually increased from a minimum distance from the cooling surface to the required final distance in such a way that the free gap between the wedge-shaped developing solidification front of the cast strip 7 and the die lip 5 remains small enough to prevent the molten metal from flowing out through the gap in an uncontrolled manner. The end face edge of the slotted die 2 can be borne via one or more gas cushions on the cooling surface and the free surface of the cast strand.

Abstract: A method for producing titanium particles (34) suitable for powder metallurgy applications by atomizing a free-falling stream of molten titanium. Prior to atomization the molten titanium (27) is maintained in a crucible (12) lined with a solidified layer of titanium (28) which separates the molten mass of titanium (27) from the crucible interior to protect it against contamination. The bottom of the crucible (12) has a nozzle (18) through which the titanium passes to form the free-falling stream. The nozzle (18) may be likewise lined with a layer of solidified titanium which maintains the molten titanium passing through the nozzle out of contact with the nozzle material further protecting the titanium from contamination. The free-falling stream of titanium is contacted by an inert gas jet (21) to atomize the stream into spherical particles (32), which are solidified and collected.

Abstract: In a hearing aid system, selected optimum parameter values are programmed into an electronically erasable, programmable read-only memory (EEPROM) (84) which supplies coefficients to a programmable filter (64) and amplitude limiter (67) in the hearing aid so as to cause the hearing aid to adjust automatically to the optimum set of parameter values for the speech level, room reverberation, and type of background noise then obtaining. The programmable filter may be a digital equivalent of a tapped delay line in which each delayed sample is multiplied by a weighting coefficient, and the sum of the weighted samples generates a desired electro-acoustic characteristic; or a tapped analog delay line in which the sum of the weighted outputs of the taps generates the desired characteristics. Acoustical feedback is reduced by an electrical feedback path in the hearing aid which is matched in both amplitude and phase to the acoustic feedback path, the two feedback signals being subtracted so as to cancel each other. Alternatively, a single filter in the forward path may be used for this purpose with a transmission characteristic equivalent to that of the programmable filter in the forward path plus the electrical feedback path. Also, the relative speech-noise content in the signals from the hearing aid microphone is sensed and binary words are generated and supplied to the programmable filter for selecting from memory a set of delay line tap coefficients that are effective to impart to the filter the appropriate frequency response for the specific environmental noise condition being detected.

Abstract: A process is disclosed in which a rectangular spacer frame (16) for insulating glass is automatically manufactured in that a tubular bar is repeatedly bent in a common bending plane (5) and its free ends (19, 20) are joined. One or both end portions of the tubular bar are deflected out of the bending plane (5) during the final bending operation so that the free ends (19, 20) are moved to such positions that said extremities are laterally spaced apart and extend alongside each other. The end portions (17, 18) of the tubular bar are then gripped and moved to positions in which they are axially aligned and spaced apart. The free ends of said end portions are subsequently joined to each other to form the spacer frame (16), which is subsequently transferred to an overhead conveyor (69) in an automatic operation.

Abstract: To reduce the noise signals of a video signal generated at the output (16) of a video head amplifier (3), the frequency response of a video replay head (1) preceding the video head amplifier is lifted by means of the parallel connection of a suitably dimensioned capacitor (10) by a resonant point in the area of the upper frequency limit of the frequency band reproducing the luminance of the video signal and the frequency response of the video head amplifier (3) is lowered in the same frequency band in such a manner that the resultant frequency response of the video replay head (1) and of the video head amplifier (3) is approximately linear up to this upper cut-off frequency and then drops steeply. For lowering the frequency response of the video head amplifier (3), a correspondingly dimensioned frequency-dependent feedback branch (17) from the output (16) of the video head amplifier to its signal input (18) is advantageously used. <IMAGE>

Each of the seals includes a U-shaped lip sealing element 50 and a U-shaped spring 56 positioned within the lip sealing element and urging the legs of the element apart into sealing engagement between the bushing and the body. The inner seal 46, which is positioned closest to the passage has the open end of its sealing element facing the passage and the outer seal 48, which is farther from the passage than the inner seal, has the open end of its sealing facing away from the passage. Each of the seals 46,48 is positioned within a recess in one of the bushings 36 and the body which has a depth less than the height of the seal while it is still in an effective sealing condition. The seals are compressible in height so that their bushings engage the body recess in a metal-to-metal seal when they are loaded and are recoverable from such compressed position to provide a tight seal when said loading is relieved. It is preferred that the seals utilize an aromatic polymer such as polytheretherketone or polyethersulfone for the lip sealing elements and an Eligiloy or nonferrous metal spring material for the spring.
